Political language, as used by politicians, does not venture into any of this territory since the majority of politicians, on the evidence available to us, are interested not in truth but in power and in the maintenance of that power. To maintain that power it is essential that people remain in ignorance, that they live in ignorance of the truth, even the truth of their own lives. What surrounds us therefore is a vast tapestry of lies, upon which we feed.

As every single person here knows, the justification for the invasion of Iraq was that Saddam Hussein possessed a highly dangerous body of weapons of mass destruction, some of which could be fired in 45 minutes, bringing about appalling devastation. We were assured that was true. It was not true. We were told that Iraq had a relationship with Al Quaeda and shared responsibility for the atrocity in New York of September 11th 2001. We were assured that this was true. It was not true. We were told that Iraq threatened the security of the world. We were assured it was true. It was not true.

The truth is something entirely different. The truth is to do with how the United States understands its role in the world and how it chooses to embody it.

But before I come back to the present I would like to look at the recent past, by which I mean United States foreign policy since the end of the Second World War. I believe it is obligatory upon us to subject this period to at least some kind of even limited scrutiny, which is all that time will allow here.

Everyone knows what happened in the Soviet Union and throughout Eastern Europe during the post-war period: the systematic brutality, the widespread atrocities, the ruthless suppression of independent thought. All this has been fully documented and verified.

But my contention here is that the US crimes in the same period have only been superficially recorded, let alone documented, let alone acknowledged, let alone recognised as crimes at all. I believe this must be addressed and that the truth has considerable bearing on where the world stands now. Although constrained, to a certain extent, by the existence of the Soviet Union, the United States’ actions throughout the world made it clear that it had concluded it had carte blanche to do what it liked.

Direct invasion of a sovereign state has never in fact been America’s favoured method. In the main, it has preferred what it has described as ‘low intensity conflict’. Low intensity conflict means that thousands of people die but slower than if you dropped a bomb on them in one fell swoop. It means that you infect the heart of the country, that you establish a malignant growth and watch the gangrene bloom. When the populace has been subdued â€“ or beaten to death â€“ the same thing â€“ and your own friends, the military and the great corporations, sit comfortably in power, you go before the camera and say that democracy has prevailed. This was a commonplace in US foreign policy in the years to which I refer.

The United States supported and in many cases engendered every right wing military dictatorship in the world after the end of the Second World War. I refer to Indonesia, Greece, Uruguay, Brazil, Paraguay, Haiti, Turkey, the Philippines, Guatemala, El Salvador, and, of course, Chile. The horror the United States inflicted upon Chile in 1973 can never be purged and can never be forgiven.

Hundreds of thousands of deaths took place throughout these countries. Did they take place? And are they in all cases attributable to US foreign policy? The answer is yes they did take place and they are attributable to American foreign policy. But you wouldn’t know it.

It never happened. Nothing ever happened. Even while it was happening it wasn’t happening. It didn’t matter. It was of no interest. The crimes of the United States have been systematic, constant, vicious, remorseless, but very few people have actually talked about them. You have to hand it to America. It has exercised a quite clinical manipulation of power worldwide while masquerading as a force for universal good. It’s a brilliant, even witty, highly successful act of hypnosis.

I put to you that the United States is without doubt the greatest show on the road. Brutal, indifferent, scornful and ruthless it may be but it is also very clever. As a salesman it is out on its own and its most saleable commodity is self love. It’s a winner. Listen to all American presidents on television say the words, ‘the American people’, as in the sentence, ‘I say to the American people it is time to pray and to defend the rights of the American people and I ask the American people to trust their president in the action he is about to take on behalf of the American people.’

The United States no longer bothers about low intensity conflict. It no longer sees any point in being reticent or even devious. It puts its cards on the table without fear or favour. It quite simply doesn’t give a damn about the United Nations, international law or critical dissent, which it regards as impotent and irrelevant. It also has its own bleating little lamb tagging behind it on a lead, the pathetic and supine Great Britain.

What has happened to our moral sensibility? Did we ever have any? What do these words mean? Do they refer to a term very rarely employed these days â€“ conscience? A conscience to do not only with our own acts but to do with our shared responsibility in the acts of others? Is all this dead? Look at Guantanamo Bay. Hundreds of people detained without charge for over three years, with no legal representation or due process, technically detained forever. This totally illegitimate structure is maintained in defiance of the Geneva Convention. It is not only tolerated but hardly thought about by what’s called the ‘international community’. This criminal outrage is being committed by a country, which declares itself to be ‘the leader of the free world’. Do we think about the inhabitants of Guantanamo Bay? What does the media say about them? They pop up occasionally â€“ a small item on page six. They have been consigned to a no man’s land from which indeed they may never return. At present many are on hunger strike, being force-fed, including British residents. No niceties in these force-feeding procedures. No sedative or anaesthetic. Just a tube stuck up your nose and into your throat. You vomit blood. This is torture. What has the British Foreign Secretary said about this? Nothing. What has the British Prime Minister said about this? Nothing. Why not? Because the United States has said: to criticise our conduct in Guantanamo Bay constitutes an unfriendly act. You’re either with us or against us. So Blair shuts up.

The invasion of Iraq was a bandit act, an act of blatant state terrorism, demonstrating absolute contempt for the concept of international law. The invasion was an arbitrary military action inspired by a series of lies upon lies and gross manipulation of the media and therefore of the public; an act intended to consolidate American military and economic control of the Middle East masquerading â€“ as a last resort â€“ all other justifications having failed to justify themselves â€“ as liberation. A formidable assertion of military force responsible for the death and mutilation of thousands and thousands of innocent people.

We have brought torture, cluster bombs, depleted uranium, innumerable acts of random murder, misery, degradation and death to the Iraqi people and call it ‘bringing freedom and democracy to the Middle East’.

How many people do you have to kill before you qualify to be described as a mass murderer and a war criminal? One hundred thousand? More than enough, I would have thought. Therefore it is just that Bush and Blair be arraigned before the International Criminal Court of Justice. But Bush has been clever. He has not ratified the International Criminal Court of Justice. Therefore if any American soldier or for that matter politician finds himself in the dock Bush has warned that he will send in the marines. But Tony Blair has ratified the Court and is therefore available for prosecution. We can let the Court have his address if they’re interested. It is Number 10, Downing Street, London.

Death in this context is irrelevant. Both Bush and Blair place death well away on the back burner. At least 100,000 Iraqis were killed by American bombs and missiles before the Iraq insurgency began. These people are of no moment. Their deaths don’t exist. They are blank. They are not even recorded as being dead. ‘We don’t do body counts,’ said the American general Tommy Franks.

Early in the invasion there was a photograph published on the front page of British newspapers of Tony Blair kissing the cheek of a little Iraqi boy. ‘A grateful child,’ said the caption. A few days later there was a story and photograph, on an inside page, of another four-year-old boy with no arms. His family had been blown up by a missile. He was the only survivor. ‘When do I get my arms back?’ he asked. The story was dropped. Well, Tony Blair wasn’t holding him in his arms, nor the body of any other mutilated child, nor the body of any bloody corpse. Blood is dirty. It dirties your shirt and tie when you’re making a sincere speech on television.

The 2,000 American dead are an embarrassment. They are transported to their graves in the dark. Funerals are unobtrusive, out of harm’s way. The mutilated rot in their beds, some for the rest of their lives. So the dead and the mutilated both rot, in different kinds of graves.

The United States now occupies 702 military installations throughout the world in 132 countries, with the honourable exception of Sweden, of course. We don’t quite know how they got there but they are there all right.

The United States possesses 8,000 active and operational nuclear warheads. Two thousand are on hair trigger alert, ready to be launched with 15 minutes warning. It is developing new systems of nuclear force, known as bunker busters. The British, ever cooperative, are intending to replace their own nuclear missile, Trident. Who, I wonder, are they aiming at? Osama bin Laden? You? Me? Joe Dokes? China? Paris? Who knows? What we do know is that this infantile insanity â€“ the possession and threatened use of nuclear weapons â€“ is at the heart of present American political philosophy. We must remind ourselves that the United States is on a permanent military footing and shows no sign of relaxing it.
